The PC version of the game was ported to the PC by Nixxes, which previously worked on the PC versions Deus Ex: Human Revolution and Tomb Raider.

The game's art technical director Jean-Normand Bucci previously said
that the Thief reboot will look better on the PC than on the Xbox One
or PlayStation 4. He explained that while Thief for the new systems from
Microsoft and Sony will deliver "much more" than what console gamers
have come to expect, the PC version will go even further.
